A 12-year-old boy was arrested Saturday in the stabbing death of his younger sister, Leila Fowler, inside their Northern California home.
The arrest came after a manhunt for a supposed intruder who the boy had said committed the crime.
"Citizens of Calaveras County, you can sleep a little better tonight," Sheriff Gary Kuntz told reporters.
The boy, whose name was not made public, will be charged with murder, the county sheriff announced at a news conference, according to the Associated Press.
The slaying made national headlines and had authorities warning residents of the tight-knit area where the crime occurred to lock their doors and remain vigilant.
Leila and her brother were home together on the night of April 27 at the family home in Valley Springs, a rural town of 7,500 residents southeast of Sacramento. Their parents had gone to a Little League game.
